From quick observation on legacy openBSC, we just accept the PERIODIC LUR for a "detached" MS and update the LAC in the HLR.
Perodic LU applies to attached MS, not detached ones.
Ah, I understand now. I got the wording the wrong way, thought you wrote "we accept Periodic LU *only* for detached MS" while you meant to say "when a Periodic LU comes in for a detached phone, we simply accept it".
Ok, yes, the idea remains: not trigger SMPP signals on the periodic-ness of the LU, but rather wherever the MSC decides to change between "attached" and "detached".
Whether a "periodic" lu is then also accepted as "imsi attach" or not is then a mere implementation detail of the MSC.
